Williams 6004MFRPHW Preset Torque Wrench 3/4 in Hex Drive

Product Description

The WILLIAMS 6004MFRPHW is a preset torque wrench built for heavy-duty fastening applications where consistent, repeatable torque delivery is critical. It uses a 3/4 inch hex drive and covers a torque range of 120 to 600 ft/lb (169 to 779 Nm), making it suitable for large fastener work in industrial, fleet, and heavy equipment maintenance environments. The 42 inch overall length provides the leverage needed at the high end of the torque range. An ergonomic comfort grip handle reduces fatigue during extended use. At 15.72 pounds, this is a full-size professional tool intended for shop or field use by mechanics, millwrights, and heavy equipment technicians.

This wrench is used in applications requiring precise torque control on large-diameter fasteners, such as wheel hub assemblies, structural bolting, heavy machinery, and industrial equipment servicing. The preset configuration eliminates the need for field adjustment, reducing the risk of under- or over-torquing in production or fleet maintenance settings where technician-to-technician consistency matters. It is appropriate for both shop bench use and on-site work where a long-handled, high-capacity torque wrench is specified by a service procedure or torque chart.

• Ergonomic comfort grip handle reduces operator fatigue during extended use

Compatibility

Designed for use with standard 3/4 inch drive hex sockets and accessories in heavy-duty mechanical and industrial fastening applications.

Installation Notes

This tool is typically used by licensed mechanics, millwrights, or heavy equipment technicians. Before applying torque, verify the fastener specification against the equipment manufacturer's torque chart. Store the wrench at or below its minimum torque setting when not in use to preserve the preset mechanism. Do not use this wrench to loosen fasteners, as reverse loading can affect calibration accuracy.
